Sometimes it is handy to have a quick overview of all the assemblies that your C# program has loaded. Maybe because you are trying to debug a version conflict, or because you want to distribute your application and want to get an idea of its dependencies.

To find the loaded assemblies we first need to determine the current AppDomain (it is possible for your application to have more than one AppDomain, but in that case you have created the second one yourself). Each AppDomain keeps a list of Assemblies it is using and in the following example code we query it using the GetAssemblies() method.

using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
AppDomain MyDomain = AppDomain.CurrentDomain;
Assembly[] AssembliesLoaded = MyDomain.GetAssemblies();

foreach (Assembly MyAssembly in AssembliesLoaded)
{
Console.WriteLine("Loaded: {0}", MyAssembly.FullName);
}
Console.ReadLine();
}
}
}

• Datagrid has built in paging sorting and editing capabilities which are not there with the other two controls.
• Datalist has a property called repeat. Direction = vertical or horizontal.This is most useful in designing layouts.
• A repeater is used when more intimate control over html generation is required.Repeater is the most customizable. It allows you to create structures like nested lists for example.
• The Repeater repeats a chunk of HTML you write, it has the least functionality of the three of them. DataList is the next step up from a Repeater; accept you have very little control over the HTML that the control renders. DataList is the first of the three controls that allow you Repeat-Columns horizontally or vertically.
• Datagrid is most restrictive as regards to customization followed by DataList and finally Repeater is the most customizable. However, instead of working on a row-by-row basis, you’re working on a column-by-column basis. DataGrid caters to sorting and has basic paging for your disposal. NOTE: DataList and DataGrid both render as HTML tables by default.
• Out of the 3 controls, I use the Repeater the most due to its flexibility. Occasionally I like using a DataList because it allows me to easily list out my records in rows of three for instance.
